Thermally insulating floating liner

ABSTRACT

An article of apparel is comprised of an outer fabric shell defining a body portion and arm portions. The body portion has a back panel section and one or two front panel sections. A thermally insulating liner is secured to the back panel section and the one or two front panel sections by tack fasteners which may form permanent or detachable connections and these connections are positioned at predetermined locations along peripheral edges of the liner. The connections provide for the liner to have large un-attached peripheral areas to provide free floating displacement of the liner with respect to the outer fabric shell when worn by a wearer person to reduce restraint of movement of the wearer person&#39;s arms and body by the outer shell and liner and thereby enhancing the wearer person&#39;s freedom of movement. In a further embodiment the tack fasteners are detachable wherein the liner can be worn as a sleeveless insulating vest and wherein the vest is provided with adjustable tie means about its arm holes, neck and bottom openings to provide sealing thereof against a wearer person&#39;s body to maintain body heat.

FIELD OF THE INVENTION

The present invention relates to insulating liners and particularly, but not exclusively, for insulated articles of apparel and to an improvement of the construction of the article of apparel to reduce restraint of movement of a wearer person arms and body by the article of apparel and its thermal insulating liner and thereby enhancing the wearer person's freedom of movement.

BACKGROUND OF THE INVENTION

The construction of thermally insulating articles of apparel, such as jackets and coats, formed with a thermally insulating liner secured inside an outer fabric shell are bulky and heavy and cause restraint of movement of a wearer persons arms and body. This makes the article of apparel heavy and uncomfortable and restraining, particularly so during sports activities where the body and arms are in continuous motion. Furthermore, where the insulating fabric material overlaps, such as in the arm pit areas where the sleeve overlaps the body portion of the article of apparel, the overlapped insulation causes the wearer person to sweat in the arm pit areas.

Another disadvantage of thermally insulating articles of apparel is that they have limited use for the reason that they provide comfort only during specific climatic conditions, for example during winter months only when temperature are very cold and below freezing. If the temperature increases above freezing then the article of apparel is uncomfortable and the wearer person must resort to the use of another article of apparel adapted to a warmer environment.

It is also known to have articles of apparel with detachable insulating fabric liners attached to the outer shell by the use of zipper fasteners whereby the outer shell can be used for a prolong period of time by the removal of the liner. A disadvantage of such insulating liners is that they further restrict arm and body movements of a wearer person due to the fact that the article of apparel is bulky and adds fabric weight when pulled by arm movements and further cause a restriction to the arm movement. Still further, the liner fabric being most often made from wool material often causes a wearer person to perspire which is undesirable.

It would be desirable to overcome the above mentioned disadvantages and to provide additional features of such articles wherein such articles may have others applications and can be used for longer periods of time with different applications.

SUMMARY OF THE INVENTION

It is a feature of the present invention to provide an article of apparel which substantially overcomes the above mentioned disadvantages of thermally insulated liners used in articles of apparel and which provides additional features, uses and applications.

A further feature of the present invention is to provide a thermally insulating article of apparel wherein the thermally insulating liner is secured by tack fastening means secured at predetermined locations inside the article of apparel to reduce restraint of movement of a wearer person's arms and body by the outer shell and liner and thereby enhancing the wearer person's freedom of movement. Such article of apparel would be of great advantage for military personnel, police and firefighters, commercial fisherman and outside workers of many trades.

A further feature of the present invention is to provide a thermally insulating article of apparel wherein the thermally insulating liner is detachably secured inside the outer shell of the article of apparel providing ease of removal and replacement of the thermally insulating article of apparel with other thermally insulating liners of different thermal insulating values.

A further feature of the present invention is to provide a thermally insulating article of apparel wherein the thermally insulating liner is in the form of a vest which is detachable secured inside the outer shell of the article of apparel and can be worn as a separate article of apparel.

A still further feature of the article of apparel is to provide a thermally insulating liner in the form of a vest which is detachable secured inside the outer shell of the article of apparel and wherein the arm holes, the rear and front panels and the neck opening are provided with cord locks for sealing the openings against a wearer person's body to maintain body heat inside the vest when worn independent of the article of apparel outer jacket shell and further wherein the cord locks can be loosen to permit ventilation and air circulation inside the vest.

According to the above features, from a broad aspect, the present invention provides an article of apparel comprised of an outer fabric shell defining body portion and arm portions. The body portion has a back panel section and one or two front panel sections. A liner is secured to the back panel section and the one or two front panel sections by tack fastening means positioned at predetermined locations of the liner whereby to provide free floating displacement of the liner with respect to the outer fabric shell when worn by a wearer person to reduce restraint of movement of the wearer person's arms and body by the outer shell and liner and thereby enhancing the wearer person's freedom of movement.

According to a further broad aspect of the present invention, the liner is a thermally insulating liner having thermally insulating material and preferably, but not exclusively formed of a composite down material sheet having a stretchable down core structure.

According to a still further broad aspect of the present invention, the tack fastening means are constituted by detachable tack fasteners to permit removal of the thermally insulating liner. Further, the thermally insulating liner is a replaceable liner with other thermally insulating liners of different thermal insulating values whereby to permit a wearer person to interchange the thermally insulating liners to adapt the article of apparel to different climatic conditions. Still further, at least two or more of the thermally insulating liners are provided for removable securement to the outer fabric shell of the article of apparel.

According to a still further broad aspect of the present invention, the detachable liner is a sleeveless thermally insulating vest having front and rear interconnected body panels defining arm holes, a neck opening and a bottom opening. The sleeveless insulating vest is formed by an outer fabric shell, an inner lining material fabric and an intermediate thermally insulation material held captive between the outer fabric shell and the inner lining material. An adjustable tie means is provided along the arm holes, the neck opening and the bottom opening to provide for adjustment of the openings wherein to permit sealing of the arm holes, neck opening and bottom openings against a wearer person's body to maintain body heat inside said sleeveless insulation vest and to further permit ventilation of the wearer person's body.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION

Referring to FIG. 1 , there is shown a jacket type article of apparel 10 comprised of an outer fabric shell 11 defined by a back panel section 12 and two front panel sections 13 and 13′. A thermally insulating liner 14 is secured to the inner surface of the back panel section 12 and the two front panel sections 13 by tack fastening means, herein permanent stitch tack fasteners 15 positioned at predetermined locations along peripheral edges 16 of the thermally insulating liner 14 whereby to provide free floating displacement of the thermally insulating liner 14 between the tack fasteners and with respect to the outer fabric shell 11 when the article of apparel 10 is worn by a wearer person to reduce restraint of movement of the wearer person's arms and body by the outer shell 11 and thermally insulating liner 14 and thereby enhancing the wearer person's freedom of movement.

As further illustrated in FIGS. 1 and 6 , the article of apparel 10 is further provided with arm insulating sleeve liners 17 secured in each of the arm sections 18 of the article of apparel 10 by detachable tack fasteners 15′ disposed spaced apart about the cuff end 19 of the sleeve 18 and a shoulder arm entry end area 20 of the sleeve 18. FIG. 6 illustrates the arm insulating sleeve liner 17 and as herein shown it is formed with a cut-out section 21 formed in a peripheral area of one of an arm pit portion 22 of the jacket 10. Alternatively, a similar cut-out portion 23 of the thermal insulation 24 and its scrim sheets 25, see FIGS. 2A and 28 , can be made in the arm pit portion 26 of the body liner between the back panel section 12 and the two front panels 13 and 13′ whereby when the article of apparel 10 is worn by a wearer person the insulation liner of the arm insulating sleeve liner 17 is not overlapped in the arm pit areas of the jacket 10 resulting in bulkiness and non-comfort in the arm pits and causing perspiration.

FIGS. 2A and 2B are cross-section views of the thermally insulating construction of the liner and as herein illustrated it is comprised of a down feather sheet 26 formed by a thermally insulating 24 core of down material mixed with binder material to form a homogeneous down sheet. A scrim sheet 25 is bound to opposed surface of the core 24. In one aspect of the present invention, there may be provided different liners having different thermally insulating values whereby to adapt the article of apparel 10 to different climatic conditions. FIGS. 2A and 2B illustrates two such liners which have their core 24 and 24′ of different thickness to provide different thermal insulating values to adapt the outer shell 11 of the article of apparel to different climatic conditions. Of course, to do so, the tack fasteners 15 are formed as detachable fasteners, some of which are illustrated in FIGS. 7A to 7D. The down material insulation sheet 26 forms part of some of my issued US patents, but other insulating material, such as synthetic insulation, may be used in constructing the thermally insulating liner.

FIG. 7A illustrates in greater detail a stitched tack fastener 15 formed by a permanently sewn thread connection 15″. FIGS. 7B to 7D illustrates different types of detachable tack fasteners 15′. The detachable fasteners 15′ may be provided by magnetic fasteners 30, as shown in FIG. 7D, and of a type well known in the art and providing sufficient retention force to prevent detachment when there is a pulling force exerted on of the liner by displacement of the outer fabric shell. Still further, the detachable fasteners 15′ may be formed by loop and hook tack fasteners 31, as shown in FIG. 70 , or snap tack fasteners 32 as shown in FIG. 7B or loop and button fasteners (not shown) or other suitable detachable attachment means.

As shown in FIG. 3 , the article of apparel 10 is herein formed with an additional feature wherein the collar 35 is formed with a concealed pouch 36 retained by a stitch seam 37 and accessible in an internal chamber 38 formed between fabric layers of said collar 35. The pouch 36 is dimensioned to receive therein the outer shell 11 with the liner detached therefrom to form one of a carrying pouch or a pillow. If the thermally insulating liner is not too thick, it may also be positioned in the pouch 36. A pouch may also be formed in the back of the liner 14 to carry, in a concealed manner, other sections of the liner, such as sleeves, a hood or other associated parts or attachments or features.

In one of its aspects, the jacket 10 has at least two thermally insulating liners 14 provided therewith with the liners being replaceable and of different thermal insulating values whereby to permit a wearer person to interchange the thermally insulating liner 14 with an other liner of different thermal insulating value to adapt the article of apparel 10 to different climatic conditions.

Referring now to FIGS. 4A to 5 there is illustrated another important feature of the present invention, wherein the body thermally insulating liner 14 and the arm thermally insulating sleeve liner 17 are displaced relative to its relationship with the outer fabric shell 11 due to body and arm movement or the wearer person. As shown in FIG. 4A, when the wearer person 40 moves its arms 41 up and down, the tack attachments 15, 15′ permit movement of the thermally insulating sleeve liner 17 relative to the outer fabric shell 11 in the direction of arrows 43 between its tack fasteners 15, 15′ and thereby providing more liberty of arm movement to the wearer person. This is also the case when the arms are displaced as illustrated in FIG. 4C where the arms of the wearer person 40 pulls on the thermally insulating sleeve liner 17. Accordingly, there is much less restraint as compared to full stitch seam securements where the full load of the shell and liner is displaced in unison by arm movements of the wearer person. FIG. 4B illustrates a further motion of the wearer person 40 wherein the body portion of the thermally insulating liner 14 provides additional freedom of movement. As herein illustrated, when the wearer person 40 bends forward its back 45 exerts a pulling friction force 47 onto the liner 14 causing the liner to move in the free liner portions 48 inwardly with respect to the outer fabric shell 11 liberating part of the jacket load onto the back 45 of the wearer person 40. Accordingly, the thermally insulating liner can be referred to as a floating liner in this respect in relation to the outer fabric shell to enhance the freedom of movement of a wearer person.

Referring now to FIGS. 8 and 9 , there is shown generally the liner 14 of the present invention formed as a sleeveless insulating vest 50. The sleeveless insulating vest 50 is formed by a back panel 51 and a right and left frontal panels 52 and 53, respectively, interconnected by a central zipper fastener 54 or other suitable fasteners, such as a magnetic zipper type fastener. The vest 50 has arm holes 55 and 55′, a neck opening 56 and a bottom waist opening 57. The sleeveless insulating vest 50 is formed of a thermally insulating construction such as described above with reference to FIGS. 2A and 28 , with an inner lining material fabric and an intermediate thermally insulation material held captive between the outer fabric shell and the inner lining material. As shown the vest, when detached, as the detachable fasteners 15′ secured thereto at different locations with relation to the openings. As herein shown the detachable fasteners 15′ are in the form of “Velcro”, registered trademark of the 3-M Company, patches 30 as shown in FIG. 7D.

With additional reference to FIG. 10 , the sleeveless insulating vest 50, as herein illustrated, is provided with an additional feature wherein an adjustable tie means, herein in the form of a draw cord 58, is trained in a retention channel 59 formed along the arm holes 55, the neck opening 56 and the bottom waist opening 57 between an outer seam edge 60 and an inner spaced stitch seam 61 interconnecting the outer fabric shell material and the inner liner material and such a channel and draw cord fastening arrangement is of a type well known in the art. As shown, in this figure, the draw cord is formed about the arm opening 55 and exits a channel opening 62 where opposed sections 58′ of the draw cord are trained through a releasable clamp cord lock 63 to permit said draw cord to cinch and lock the arm retention channel 55 about a wearer persons arm. Such cord locks are well known in the art and are provided about all of the openings to seal the vest about a wearer person's body to maintain body heat inside the sleeveless insulation vest and to further permit ventilation of the wearer person's body by releasing or adjustments to some or all of the cord locks

Preferably, but not exclusively, the sleeveless insulating vest 50 is formed of an outer fabric shell which is a waterproof and breathable synthetic fabric material, an intermediate insulation material formed by a down material sheet having a self-supporting core mixture of down feathers and a binder throughout and an inner synthetic fabric material. The down material sheet is a also preferably a stretchable sheet as described in my U.S. Pat. No. 9,380,893, issued on Jul. 5, 2016 and which provides multi-directional stretchability to prevent fragmentation of the core mixture by body movements of the wearer person. Such a self-supporting down core mixture being formed as a uniform sheet throughout is free of cod spots formed by down material retention stitching which is illuminated by this down sheet structure.

As shown in FIGS. 8 and 9 , the sleeveless thermally insulating vest 50 is further provided with a hood 65 secured about a collar 66 formed at the neck opening 56 with the hood defining a face opening 67. The hood 65 is also formed with thermally insulating material of the like as described above with respect to the thermally insulating structure of the vest. An adjustable tie assembly 68 of the type shown in FIG. 10 is provided along a channel 69 formed along the outer edge 70 of the face opening 67 to provide for adjustment of the face opening for sealing the hood 65 about the wearer person's face by the adjustable cord lock 63′ to provide warmth to the wearer person's head. Similarly, a draw cord 58 is trained in a channel 69′ formed about the bottom edge of the neck collar 667 and made adjustable by the release cord lock 63″ to substantially seal the neck area of the wearer person.

Referring to FIG. 11 there is illustrated a further embodiment of the construction of the arm sections wherein they are fabricated as a one-piece arm section insulating liner 75. The one-piece arm section liner 75 is comprised of arm sections 76 and 76′ interconnected together in a predetermined spaced-apart relationship, depending on the size of the outer fabric shell 14, by an intermediate back panel 77. The arm sections 76 and 76′ are also sized to fit the outer shell sleeves 18. Tack fastening means in the form of magnets 78 are secured to the back surface of the back panel 77 to interconnect with associated magnets of opposed polarity secured to the inner surface of the back panel section 12 of the outer shell 11.

It is within the ambit of the present invention to provide any obvious modifications of the embodiments described herein provided such modifications fall within the ambit of the appended claims. As examples only, the thermally insulating liner 14 can be formed with sections having different thermal insulating values, ie., the back section having an upper portion thicker than the bottom portion to provide more warmth in the upper back of a wearer person. The liner could also be formed with thermally insulating flaps to overlap the non-secured peripheral portions of the liner to provide insulation over the displaced areas of the liner where cold spot areas may form during displacement of the liner. The thermally insulating sleeves may also be formed by a single flat thermally insulating sheet which is overlapped by the user person and secured by strip attachments, such as magnetic strips or “Velcro” (loop and hooks), registered trademark of the 3-M Company. As described, the collar of the jacket may permit the article of apparel or the shell only thereof, to be concealed in a pouch to convert the collar to a pillow to provide comfort to the user person such as when traveling in an aircraft, bus, etc. The outer fabric shell may also be formed with stretchable material sections to provide for additional freedom of movement working in concert with the thermally insulating floating liner.

It is also within the ambit of the present invention to provide a sleeveless thermally insulating vest having front and rear interconnected body panels defining arm holes, a neck opening and a bottom opening. The sleeveless insulating vest is formed by an outer fabric shell, an inner lining material fabric and an intermediate thermally insulation material held captive between the outer fabric shell and the inner lining material. An adjustable tie means is provided along the arm holes, the neck opening and the bottom opening to provide for adjustment of the openings wherein to permit sealing of the arm holes, neck opening and bottom openings against a wearer person's body to maintain body heat inside said sleeveless insulation vest and to further permit ventilation of the wearer person's body.

The floating liner concept of the present invention is also intended to have different uses such as for providing a thermally insulating barrier to tents to keep warmth in winter months and to keep the tent cool in summer months while expelling humidity. For such an application the down sheets would be fabricated as panels and retained to the walls of the tent by tack ties which may be permanent or detachable, as above described. The panels would be uniform thickness throughout and maintain this uniformity and thus eliminating cold spots formed by stitching or manipulation. The panels being formed from down feather material would be thinner than ordinary synthetic or natural insulating material making them light weight and easily packaged in small carrying bags or pack sacks. The panels could also be fabricated with different CLO counts to adapt the tent to different climatic conditions and provide for a quick adaptation to changing harsh climatic conditions, such as we find in the State of Alaska, for example. This would be of great asset for military use and commercial applications.

Many modifications and other embodiments of the present invention as described above will come to mind to a person skilled in the art to which the invention pertains having the benefit of the teachings described herein above and the drawings. Hence, it is to be understood that the embodiments of the present invention are not to be limited to the specific examples thereof as described herein and other embodiments are intended to be included within the scope of the present invention and the appended claims.
